fuel line break at filter - is there a compression fitting fix?
 

i was replacing my fuel filter today and the metal line broke a couple inches from the filter. (pic) is there a compression coupling that can be used as a fix instead of installing entire line? thanks in advance

Quick fix: get short piece of fuel hose and 4 clamps. Cut metal line ends back about 1/4" to get to undistorted area. File ends smooth. Blow out any debris/metal filings. Install hose so it overlaps metal lines by 1" min, put two clamps on each end. Will probably outlast the car.

Make sure it is rated for fuel and not just standard vacuum hose.

thank you fellas...always good to get fresh perspectives. off to the store.

If you happen to have a flaring tool, a very slight flare on each end would provide a little more security against leakage. Over time clamps and hose can loosen and having a lip would help keep things from sliding apart.

Because of the potential for fire, I would consider a more permanent repair.

Is this safe on a fuel injected car?

The hose needs to be fuel injector rated pressures not just normal fuel hose. You can also take the fuel line to a local hydraulic hose shop and they can put a crimp fitting on it to connect the two or make you a braided hose to take the metal's place. Not a lot of money to do that.

I would recommend doing what Don says...

Don't become a statistic, buy a new part. JMHO. There are too many 911's burning to the ground as it is.

thank you guys. i will do the hyd. shop route next week...do you think ill be alright with regular fuel hose for the weekend (just driving to work and back)? the fire thing scares me too...i put a extinguisher in the car to combat "Murphy"...but will do it right on monday. thank you again for the replies.

McG: Fabric reinforced DOT approved FUEL line of a size that will provide a snug fit should be fine. There are flexible fuel hoses all over fuel injected cars. Important that you use two clamps at each end for safety in case one lets go. That said, The above is only my opinion, it is what I have done on occasion to my own vehicles. It is not a solicitation for anyone to do what I have done in the past. My stated advice is to have your vehicle taken by flatbed truck to the nearest Factory licensed Porsche dealer and have them replace whatever parts they feel that they should, for whatever reason they feel is in the interest of the safety of you, the customer, and warranty their work for as long as said vehicle shall be in an operational state on this planet.
Amen!
I don't know nuthing!!

LOL... now there's a disclaimer and a half. :)

It's not the flex hose that rouses caution, but how things are held with worm clamps. Crimped flex fittings are fine. Cheap worm clamps are notorious for failing, rusting, and can be easily over tightened to the brink of breaking/stripping. Misting fuel vapor is everyones worst nightmare.

Who said anything about "cheap" worm clamps? There's lots of good s.s. clamps holding important stuff together on boats of all sizes. All s.s. clamps are available at boating supply houses and "real" hardware stores. Just take a magnet with you to make sure they are ALL stainless. Some are labled "stainless" right on the clamp, but the "worm" screw is plain carbon steel. But even so, it shouldn't be that big an issue as long as you keep your car out of salt water! The clamp size for fuel line is small, so don't over-torque them, and ck them every month or so. Again, standard boating practice is to double up the number of clamps on any hose that, if it came undone, could cause the boat to take on water or catch fire. Boats and airplanes, the two conveyances that you can't pull over to the side and get out if something goes wrong!!
Lots of hose clamps in both of them!!

That looks like a 10mm metal line. If so, I have something I use to repair 944 fuel line/hoses that might work.
It is not a compression ring but a Metric flare fitting, although it requires using a 10mm Metric flaring tool.
If you can post a photo of the other half of the metal line I could tell better.
If someone can tell me how to add a link to a web page I can show anyone who might be interested.
Is this on a 911SC?

Take it to your local Ford Dealer!!! (Only if you want it to burn along with all the F series trucks) LOL

Braided fuel line are in use all over the world in cars, planes and boats. Porsche even crimps a rubber hose to the fuel line where it connects to the fuel pump. I wouldn't worry about using them if I were you. Under a hundred pounds pressure is nothing. But if you have a lot of money, feel free to buy the factory replacement.
